I've moved to a new web site:
Academy of Lagado at https://sites.google.com/site/lagadoacademy/home
Blogger is nice, but I have found it too limiting for what I would like to do, so I have moved to Google Sites instead. All of the information found on this blog has been copied to the above web site, together with new information.

In this post I will show how to build a lathe tool for turning spheres (balls) and other curved surfaces, and provide links to measured drawings.
